As always with ETrailer, we received great assistance and accurate information. The water heater took a couple of hours to install as a couple of adjustments needed to be made to get it into the space. We are up and running again thanks to ETrailer and Andy!

It’s working perfectly!

by: Colton 09/29/2026 One Year Later

Install was easy. Only disappointment is that when the propane burner is running to heat the water, a light howling like noise comes from the heat exchanger. Not a huge deal just something future buyers should be aware of beforehand. Super satisfied with performance, this one makes a full tank of hot water in about 20 minutes or less.

by: Clayton 05/18/2026

I'm giving this 4 stars, because The water heater and door kit work to replace my leaky Atwood water heater. By comparison, this beats the Atwood by a large margin. The drain cap is very easy to get to, for winterizing.
Now, I held back the 5th star only because I've had to redo the plumbing. I know, that would have been asking too much, but I also would have gone with 5 stars, if the color of the door matched my RV. *wink*

I'm always one who loves to customize things so I totally agree that more color options should be available for the doors.

by: James 07/10/2026

Propane works great! The electric side not as hot water easy install, yeah right. Takes knowledge to install, which I have , the rerouted propane line was a challenge, under carriage to redo line and flare fittings , also a better description of wiring of gas and electric low voltage, I went with colors to match but didn’t want to damage unit

by: Bruce 07/27/2026

Arrived a day early... GREAT!!! MFG packaging brought the rating to a 4. The mounting flange was bent on 3 of the 4 sides, due to no additional packing inside the mgr box. The flange was easily bent back into shape.
Install was straight forward, per mfg instructions.

by: Stephen 07/22/2026

Water heater was delivered yesterday. I just installed it for a customer this morning. Everything went smoothly. Tested the water heater before finishing sealing up the outside flange with butyl and screws. Heater was working great on both propane and electric. No leaks the customer was very happy to have it working again.

by: Corey, Master RV Services 08/13/2026

Water heater showed up on time, it was the the right application due to Atwood being bought out by Dometic, fit perfect with conversion door.

i had to replace my Atwood Water Heater again thanks to the extremely HIGH calcium content in the water where i was living in Northern California. This NEW water heater was a simple install. Everything fit perfectly and i had it going in about 2 hours. NO complaints what so ever. it works Great.

everything still working perfectly. NO complaints what so ever

by: Jimmy 08/31/2026

The Dometic design is mind boggling!!
1-why the electric plug?
2-why put the propane heat disbursement at the top which makes no sense because it could and will burn the RV. The flange is not very thick to stop that.
3- they couldn't fit the original hole that Atwood had? So we have to retro fit it with additional sides. The thermostat seems to run hotter.
It's not the sellers fault, it the maker.

The purchasing and shipping process for etrailer was amazing. I made this purchase over a weekend to have it arrive on a Wednesday as the website indicated. There was a problem processing a payment and I was contacted several times by Andy to ensure the problem was rectified and the heater was shipped in a timely fashion. My water heater arrived a day earlier than they estimated on top of the processing issues and once it was delivered, I received an email confirmation which also included a link to documents related to the installation process

I only had two minor issues with the heater, but they do not negatively affect etrailer.com. It arrived with mounting options for the front door on the top corners instead of with the center tab as indicated in the pictures and also how my previous heater was setup. I thought it was going to be an issue as I didn’t purchase a new door, but I just moved one mount to the center position.

Second, this water heater did not come with any mounting screws. I’m sure that’s Dometic’s choice and I was able to reuse my old hardware. So just a heads up for anyone in the future.

Overall, thank you etrailer.com, everything worked out great!
The install process was easy and it’s working better than my old heater ever did.

That is so great to hear, Robert - glad Andy was able to help you out on this order and keep you in the loop! It's good to know what actually comes with it. Having the heads up is nice for other folks to have! Glad you have hotter water than ever ;)

by: Sherry 03/22/2024 One Year Later

It's been one year since we replaced the water heater in my 2006 Jayco Feather and there are no complaints. The new water heater is working great and etrailer was a huge help when I purchased it. If you're replacing a water heater, I would read the Question and Answer section on here for the model you are going to buy. And also pay close attention and figure out if your current water heater door will work with the new water heater. They may vent in different places.

This water heater started leaking underneath the tank shortly after I posted this review. I was out of state and couldnt do anything about the leak until I returned home. I called Dometic to see if they had any advice for repairing the leak. The person I talked to said the tank may have had a bad weld on the seam, it was out of warranty, no advice, and basically not their problem. I wont buy this brand again. The original Atwood water heater lasted for 20 years. Its not the fault of eTrailer, they were great.

by: RJ Sailor 08/11/2026

It appears just fine. I have not yet installed it, but based on other reviews im sure it will be fine.

by: Debra 09/22/2026

So far so good!!

by: Jeremy 07/24/2022

My water heater leaked and It was the old style that is no longer available. This one needed some conversion but it fit. I even made a pan to go under it in case it leaked again.
I used two 1/2” supply lines to make the connections because they were in different locations. Worked like a champ!
Had to use the door conversion which fit perfect.

Glad to hear that the team got you sorted so you could get a new one faster, David! Have you been able to test it out yet on a trip?

This water heater was meant to replace an older Dometic model which was heavier and had a larger opening. We appreciate the new style and feel it works well. We had to buy a door conversion kit. E-Trailer was wonderful in getting it shipped in a prompt fashion. We have just a few recommendations for Dometic for this model. 1. Please provide a silver colored door conversion kit for Airstreamers. We ended up painting it with a high heat silver spray paint. Just added unnecessary steps to the install. 2. Please provide self-tapping screws for the actual unit to be put back in place. Our older model had 10 screws and we used them all, and then some. So, we ended up halfway thru the install only to find out we were missing 10 screws. None of the holes in the new frame lined up with the old model. Also, a bit annoying. It would be great to include electrical connectors to snap the wires together and include a low profile outlet to plug the new model into. We were able to cobble things together from Home Depot, Lowes, Menards...but it would be even better if these items were offered or suggested by e-Trailer during the purchase. And we can add Butyl tape to that list. 3. We also wish the door conversion kit was a bit more seamless. We screwed in the corner supports on the water heater, only to find out we needed to take them back out and use the door kit corners. Again, the product is better but the devil is in the details. Glad this project is done.

Thanks great item every thing worked out

by: John 05/26/2025

Needed a water heater and this was the best one to fit, after reading the directions front to back it took only a couple hours total to get it in my RV. Water heated up immediately and everything has run great, of course it's only been a few days but so far so good, my only issue is that there is a back order on the door cover.. so it's totally exposed to any elements and I have put temporarily back on the door that came with the RV ( even though it doesn't fit) it's just so it's not totally a open hole to the outside, hoping it is available sooner than later.

by: Patrick 07/01/2025

Installation was easy, I did have to raise cabinet drawer up about 1 inch to allow clearance at the back for the water connections. It is quieter than my older (2000) Dometic and hot water recovery is a little faster.

Easy installation! Works great!

by: Donald 01/14/2022

We have Hot Water ! We live in our RV full time so we needed a Hot Water Heater of good quality. Time will tell if this Dometic Hot Water Heater is as good as the old Atwood which it replaced. The packaging was good ! Hot Water Heater appears to be well made. No problems installing the directions were clear and it fired right up. This replacement Hot Water Heater is smaller than our original so we purchased the enlarged door kit which fit perfectly. Great communication with etrailer which helped us find the correct Water Heater for our application. There website information was accurate and we had no problem contacting a human voice when needed.. We are Happy Campers !

One Year Later ~ Hot water Heater is working very well. Pros~ This replacement water heater seems to recover faster than the original. My previous hot water heater was only propane gas so this one has the electric option which works well. Cons~ Burner flame blows out when we have a 20 plus MPH. east wind directly. There are no flame adjustments just a circuit board which controls all the settings.. This hot water heater needs a external wind screen protector to mount over the door to keep the burner flame from blowing out..

Water Heater with Tank Recommendation for a 2024 Grand Design Reflection 337RLS
Hey Roger, thanks for reaching out! The Dometic RV Water Heater with Door Kit # DMC43RR is the best replacement we have for you since it works with gas and 12V power. It does fit a 12-3/4" tall x 12-3/4" wide x 19-7/8" deep cutout so you'll just need to compare that to what you currently have and see what type of modifications you might need to make. Are you planning on doing the installation on your own, or having a tech install it for you?

Replacement Water Heater for Atwood G6A-3
Hi Devon; all of the Atwood G6A models are 6 gallon water heaters with some slight variation within the models which is why you see the Dometic # DMC74FR (Gas/Electric) or # DMC39RR (Gas only) recommended as the replacement. The same is true for your G6A-3. I don't have a lot of information on the G6A-3 but I would choose a replacement based on whether your current model is gas or gas/electric. You also want to check your current cutout. If you have a 16-1/2" wide cutout you want the...

What Is a Direct Replacement Water Heater for a 2020 Grand Design Transcend Xplor 243BH?
Hello Kenneth, Thanks for writing in. I don’t have a database that shows exactly what was installed in every camper, but based on my research, your 2020 Transcend Xplor 243BH most commonly came with a 6-gallon Dometic (Atwood-style) water heater. Because of that, the Dometic # DMC43RR you’re looking at is going to be your best replacement. This unit is designed to match the standard Atwood 6-gallon footprint, with a cutout around 12-5/8 inches tall by 16-1/4 inches wide and about 20-1/2...
